ORGANIC COMPOUND FOR LIGHT-EMITTING ELEMENT, LIGHT-EMITTING ELEMENT AND IMAGE DISPLAY

Title:

ORGANIC COMPOUND FOR LIGHT-EMITTING ELEMENT, LIGHT-EMITTING ELEMENT AND IMAGE DISPLAY

Document Type and Number:

Japanese Patent JP2007269734

Kind Code:

A

Abstract:

To provide a light-emitting element having an optical output of high luminance with ultrahigh efficiency.

A new organic compound for the light-emitting element is composed of a metal complex having a monovalent bidentate ligand. The light-emitting element has at least a pair of electrodes composed of an anode and a cathode and a layer composed of an organic compound sandwiched between the pair of the electrodes. In the light-emitting element, at least one layer composed of the organic compound contains the metal complex represented by structural formula of the figure. An organic EL device (organic electroluminescent device) comprises the light-emitting element in which the layer is a light-emitting layer.
